If Evan Johnson had his druthers, we're guessing he wouldn't have chosen to become the subject of a recent feature story by The Wall Street Journal. The piece chronicles Evan's cancer treatment journey and the "new directions oncologists are taking with genetic testing" to "find and attack" tumors like his that are resistant to other treatments. It's been a difficult and unwelcome journey, but woven into his story is hope and the potential of genetic testing in tailoring cancer treatment.

Evan's infection eventually went away, the Journal reports, and opened up the opportunity for a stem cell transplant. After the transplant failed, Evan's care team at Mayo enrolled him in a clinical trial of "an experimental AML drug." That gave him a period of normalcy. "Free of toxic chemotherapy, his hair came back," reporter Ron Winslow writes. Evan also started to regain some of the 55 pounds he'd lost since coming to Mayo.

As preparations for a second stem cell transplant progressed, the Journal reports that Evan's doctors saw something in his blood work that made them fear his cancer was "evolving." Following genetic clues, Evan’s care team regrouped and worked to "revamp" his treatment plan. Eventually, "taking a suggestion from a national expert panel on AML," Winslow writes, his care team at Mayo included "a drug that hits" both the gene mutation thought to have originally led to his leukemia and a genetic alteration associated with chronic myeloid leukemia, called the Philadelphia chromosome. The results, thankfully, were more promising this time around and helped lay the groundwork for a second stem cell transplant. According to the Journal, "recent tests suggest" Evan finally now "has a chance of a sustained, durable remission."

Though Evan's cancer journey was filled with more ups and downs than they would have preferred, his father tells us there was always one constant along the way-- the family's unwavering trust in Evan's care team at Mayo Clinic. "From the second we got to Mayo Clinic, we put all of our trust into his care team," he says. "We knew he was getting the best treatment possible and that Mayo was the only place where he could have been given the best chance to survive all of this."
